The new fncpy API is better suited* for copying some
code to SRAM at runtime. This patch changes the ad-hoc
code to the more generic fncpy API.
*: 1. fncpy ensures that the thumb mode bit is propagated,
2. fncpy provides the security of type safety between the
original function and the sram function pointer.
Tested OK on OMAP3 in low power modes (RET/OFF)
using omap2plus_defconfig with !CONFIG_THUMB2_KERNEL.
Compile tested on OMAP1/2 using omap1_defconfig.
Boot tested on OMAP1 & OMAP2
Tested OK with suspend/resume on OMAP2420/n810
Boots fine on osk5912 and n800

The SRAM PA addresses are locally defined and used at
different places, i.e. SRAM management code and idle sleep code.
The macros are now defined at a centralized place, for
easier maintenance.
Tested on N900 and Beagleboard with full RET and OFF modes,
using cpuidle and suspend.

Generalize the copy of SRAM functions into omap_push_sram_idle()
so it can be used on init but also after off-mode transitions.

Move the remaining headers under plat-omap/include/mach
to plat-omap/include/plat. Also search and replace the
files using these headers to include using the right path.
This was done with:
#!/bin/bash
mach_dir_old="arch/arm/plat-omap/include/mach"
plat_dir_new="arch/arm/plat-omap/include/plat"
headers=$(cd $mach_dir_old && ls *.h)
omap_dirs="arch/arm/*omap*/ \
drivers/video/omap \
sound/soc/omap"
other_files="drivers/leds/leds-ams-delta.c \
drivers/mfd/menelaus.c \
drivers/mfd/twl4030-core.c \
drivers/mtd/nand/ams-delta.c"
for header in $headers; do
old="#include <mach\/$header"
new="#include <plat\/$header"
for dir in $omap_dirs; do
find $dir -type f -name \*.[chS] | \
xargs sed -i "s/$old/$new/"
done
find drivers/ -type f -name \*omap*.[chS] | \
xargs sed -i "s/$old/$new/"
for file in $other_files; do
sed -i "s/$old/$new/" $file
done
done
for header in $(ls $mach_dir_old/*.h); do
git mv $header $plat_dir_new/
done
